Hi,
1- Actually I am using the followings
make(8,8,1000*sizeof(float))
make3(4,4,1000*sizeof(float),1000*sizeof(float),4*sizeof(float))
I think this should also work, shouldn't it?
2- Under the general work function I am using the followings:
const float *in1 = (const float *) input_items[0]
...
float *out1 = (float *) output_items[0]
Does this part need to be changed since I am working with the vectors?
Thanks,
Ali
